We know that Service Orchestration plays an important role in next-generation networking, but it’s also important to understand the three core components of the next-generation connectivity infrastructure in more detail.
Software-Defined Networking (SDN)
SDN is a new open standards and vendor-neutral approach to computer networking that allows network operations personnel to manage network services through the abstraction of lower level functionality.
Benefits of SDN:
- SDN is directly programmable, as it decouples control from the forwarding plane. This enables operations to be dynamically controlled, giving network operators an unprecedented level of network service agility.
- SDN is centrally managed by SDN Controllers and programmatically configured by network managers using well-defined interfaces.
For more information on SDN, view the CENX Software-Defined Networking data sheet.
Network Functions Virtualization (NFV)
NFV leverages infrastructure virtualization technology to consolidate network equipment onto industry-standard servers and storage.
NFV is being used is to decouple hardware and software in traditional network equipment and provide Customer Premises Equipment (CPE) router functionality on a standardized, Commercial Off-the-Shelf (COTS) server. This transition is being driven by the European Telecommunications Standards Institute’s (ETSI) Industry Specification Group for NFV (ISG NFV).
Benefits of NFV:
- By consolidating network equipment onto industry-standard servers and storage, network design becomes much more agile, and negates the classic problem of hardware-based appliances reaching end of life.
- It decreases capex by leveraging COTS servers as network infrastructure while powering agile, on-demand network design and implementation
Service Orchestration introduces end-to-end lifecycle management of advanced data services, powering automated service planning and fulfillment and service management and assurance tools that enable the migration to SDN/NFV infrastructure.
Service Orchestration is being developed and defined by the Metro Ethernet Forum (MEF) and plays a critical component of MEF’s vision of The Third Network, a Network as a Service (NaaS) infrastructure combining SDN, NFV, and Service Orchestration innovations.
Benefits of Service Orchestration:
- Provides service providers with agile, assured, and orchestrated advanced data services.
- It empowers the delivery of new, dynamic, on-demand services with Internet-like agility and Carrier Ethernet (CE) 2.0-like service performance.
- Delivers automated services across service provider networks, ensuring high quality experience in networks leveraging access vendor infrastructure, such as mobile backhaul.
Combining the 3 Core Components
Only by combining SDN, NFV, and Service Orchestration components can service providers achieve their goal of providing differentiated and quality-assured services to their customers while reducing capex and opex and simplifying network management.
